A handlebar gear shifter for a bicycle includes a tabular handlebar having a support plate extending from an end of the handlebar at the top of the peripheral thereof. A sleeve is rotatably mounted to the handlebar. A fan-shaped mediate member has an end pivotally connected onto the support plate. A first cable has one end thereof engaged with a recess in the sleeve and the other end of the first cable is engaged with the mediate member. A second cable connects between the mediate member and a derailleur mechanism. A C-shaped member having notches is connected to the handlebar. A spring member is engaged with the sleeve.

A technique is provided that can avoid radio zone interference in a radio controlled model apparatus, which employs the frequency hopping system in the spread spectrum radio techniques. In the controller for maneuvering, for example, model airplanes, a process for detecting whether or not a radio zone is in an occupied state is initiated, with an initial radio zone represented by information (M) stored in a nonvolatile memory, acting as a starting point. Until an unoccupied radio zone is detected, the process of detecting occupation of radio zones continues, according to a predetermine sequence. Thus, an available radio zone can be detected. Moreover, information (M) representing an initial radio zone, stored in a nonvolatile memory, is updated immediately after power-on of the controller.
